As a senior in high school, [Owen] has been waiting to hear from the colleges he applied to for months now. Some of his applications wanted a mid-year report to see if he didn’t come down with senioritis. [Owen] realized these colleges allowed additional materials beyond a high school transcript, so he built a tiny [...]

[Owen] has a fairly big project in the works, where he’ll need to use infrared light to send data wirelessly between two nodes. The only problem with his grand plan is that he has never built anything of the sort. As a learning exercise, he decided to try his hand at building a wireless control [...]

[Owen] just finished putting together a portable helicopter game. It’s pretty impressive, especially since he used an ATtiny13 microcontroller. That chip uses an 8-pin dip package, offering only five I/O pins (six if you use the reset pin) and 1k of programming space. The game runs on a small cellphone-type LCD screen. The helicopter remains [...]

Sadly, this pocket mp3 wav player doesn’t come close to the capabilities of even an iPod generation 1 yet, but you have to give [Owen] props for making it in less than 24 hours. The system consists of a Propeller MCU (cleverly wired to be swappable with “shields” similar to Arduino systems), SD card for [...]

[Owen] contacted us to show us his site dedicated to his CO2 laser cutter build. He spent about 2 years and roughly $15,000 putting it together, so this is not small build. The laser and optics alone were $9,000. This site isn’t necessarily meant to be a template to build your own, but he shares [...]

[Owen] got down and dirty by adding a touchscreen to his TI-84 graphing calculator. The dirty part is the z80 assembly code he wrote to use the linkport as a UART (assembly always makes us feel queasy). Once that was working he implemented some commands using an Arduino and then hooked up an Nintendo DS [...]
